Here are some of the standout products from our vent cover category:

Emergency Vent Covers

Designed to protect tanks from potential overpressure or vacuum scenarios, our emergency vent covers are vital components for storage tank safety. The range includes:

  • KSPC Type KSEVK Pressure Vacuum Relief Emergency Vent Cover – This vent cover, suitable for air, gas, and liquid environments, comes in sizes ranging from DN400 to DN6001.
  • KSPC Type KSESV Pressure Vacuum Relief Emergency Vent Cover – This variant stands out with its high operating conditions, reaching a maximum of +9,500/ – 700 mmW.C1.

End-of-Line Flame Arresters

Ideal for applications where the venting system ends in the open air. They prevent flames from igniting vapours within the system.

Inline Flame Arresters

Designed to be installed within the pipeline, they stop the propagation of a flame from one part of the process to another.

Pressure Vacuum Relief Valves

These valves protect your tank from pressure or vacuum overloads. They open and close at set pressure and vacuum levels to ensure your tank operates within safe operating limits.

All our products in this category meet the API 2000 standards, ensuring their quality, safety, and efficiency. Trust Pressure Systems for your flame arrest-event cover needs. We are dedicated to providing reliable, effective, and high-performing solutions that meet and exceed industry standards.

With over 40 years of experience in the field, our brand is synonymous with excellence and provision of process safety-based solutions. Our commitment to innovation is manifested in the operation of the world’s largest research facility, where developing customer-specific solutions is our specialty.

Trust Pressure Systems for Your Emergency Vent Covers

When it comes to safety and precision, there is absolutely no room for second-guessing. Pressure Systems should be your top choice for superior vent covers.

40+ Years of Experience

Over the past forty years, we’ve watched safety rules evolve. And each time we’ve gone back to the bench, tweaking designs, running fresh trials and refining every detail. You can trust that our emergency vent covers are up to date with industry standards and can keep your operations safe.

Proudly Australian Owned

Still owned and managed right here in Australia, we share the same weather extremes and operational pressures you face. We’ve seen how salt-laden sea breezes can pit metal on the coast, and how an outback sun can warp lighter alloys, so we hand-pick every material, finish and gasket to suit local conditions.

Rapid Procurement

When a line goes down, waiting isn’t an option. That’s why we’ve set up fast lanes through our network of contacts so we can ship standard parts or custom assemblies in a matter of days, not weeks. You’ll have what you need, when you need it.

Tailored Industry Solutions

Our commitment extends beyond providing reliable emergency vent covers. We offer solutions specifically designed to meet the unique needs of your industry. No cookie-cutter solutions—just gear that works exactly where you need it. We build each Emergency Vent Cover around your process. High pressures, unusual vapour mixes or corrosive environments? We’ll swap in the right internals, adjust port sizes and add protective coatings until it slides seamlessly into your system.
